After experiment with semi stand film negative development, I got interested on explore the possibilities of archiving more tonalities through development process, as well as have more control on shadow and highlights.

Inspired by some info I found about exploring the curves tones with Rodinal developer, I am now experiment with the idea that, whiling photographing the exposure setting has more impact on control the middle tones of the image. The highlights and shadows can then be controlled in a more effective way during film development, where film agitation during development will have more effects on highlights and development time more effect on shadows.

Follow this concept, I develop the negatives I test agitating way much less. Instead of agitating every minute I agitate every five minutes for about 10 seconds, this will hold more information on highlights. As compensating the lower activity of the develop with less agitation, the development time is increase by 50% so the developer can work on the shadows areas of the image.

I didn't get a great result yet because the middle tones are resulting a bit dark, I will try over expose a little bit the image when photographing to see if I correct it and I hope I get a final conclusion with a good result of it.
